ERF (truck manufacturer)

ERF was a British truck manufacturer. It was established in 1933 by Edwin Richard Foden from whoms initials the company was named. Its factory in Middlewich closed in March 2002, and it was discontinued as a marque by owner MAN in July 2007.

In 1881, the first Foden traction engine was built in Sandbach. Then in 1898, Edwin Richard Foden influenced future truck design by designing the first steam wagon running on steel tyre wheels which had been successful until 1913 when vulcanised solid rubber tyre development had advanced to the stage of allowing their fitment on heavy vehicles.

Edwin introduced the first pneumatic tyred Foden steam wagon, but as steam transport appeared to be going out of favour, Edwin turned his attention to the development of a 6 to 8 ton chassis fitted with new Gardner LW (Light Weight) high speed oil engine.

At the beginning of the 1930s, Britain's industry was struggling to survive the worst recession in many years and unemployment exceeded two million. At this time insurers were becoming increasingly reluctant to underwrite steam boilers. As a result, Edwin believed the future of the lorry building industry lay in diesel engine power. The Foden boardroom did not agree, and consequently he resigned along with his son Dennis.

With the help of his son Dennis and two former colleagues, including Ernest Sherratt who became Chief Engineer, Edwin worked to build the first ERF diesel lorry in 1933, and gave the first chassis the number 63 which was Edwin's age. From the beginning, the company bought components only from other suppliers rather than manufacture itself, including engines from Gardner, gearboxes from David Brown and axles from Kirkstall Forge Engineering. This concept would serve ERF well throughout its existence.

A new cab was styled by Sandbach coachbuilder John Henry Jennings, who also provided initial factory space to assemble the new lorry. Based in Sandbach, the company made its own chassis and cab. The cab structure was made in Northampton at Air Flow Streamlines and fitted out by ERF in Sandbach. The engines from Gardner, but later also Cummins, Rolls Royce, Perkins, Detroit Diesel and Caterpillar.[1]

ERFs used to be marketed under the Western Star badge in some countries such as Australia.[2] It also built a specialist fire engine chassis, with a body built on by in-house company JH Jennings, later Cheshire Fire Engineering. However, when recession came in the beginning of the 1980s, and production fell from a total output of 4,000 chassis per annum, CFE was sold to management to eventually become Saxon Sanbec.

ERF was never a major manufacturer; as an example its domestic sales total reached only 1,083 trucks in 1981.[3] The company was bought by Canadian truck maker Western Star in June 1996.[4] However, after Paccar's purchase of Foden, DAF Trucks and Leyland Trucks competitive pressure increased, and after Western Star was approached by Freightliner Trucks, the decision was made to sell ERF.

Purchase by MAN

In March 2000, ERF became part of MAN, with production moving to a new factory in Middlewich.[5] It was later discovered that fraud had occurred at ERF, and its financial position had been incorrectly stated, with MAN winning a legal case against Freightliner.[6][7] Freightliner in turn tried to sue Western Star and ERF's former auditors Ernst & Young, but failed on the grounds of corporate negligence.[8]

Final model range

ERF's final model range consisted of the ECT, ECM and ECL built on MAN's production line in Munich (for heavy trucks), and a plant in Middlewich for light trucks, positioned to win a contract from the Ministry of Defence for 8,000 new British Armed Forces trucks. All the ERF trucks were based on MAN's existing products, the only difference being that the ERF model came with the option of specifying use of Cummins ISMe power plant.

This was as an alternate to MAN's own D20 common rail power plant. The factory in Middlewich closed in March 2002, with production of the ECT moved to Munich, Germany, ECM and ECL units moved to Steyr, Austria, where they are built on the same facilities as their identical MAN counterparts.[1][9]

In the light of Cummins' intransigence on upgrading the ISMe engine to comply with the Euro4 emission regulations, MAN initially decided to replace it completely with the new series of MAN D20 engines.[10] With ERF badging used for only the market in the United Kingdom, MAN decided to cease supplying ERF badged trucks onwards from July 2007.[4][11]
